ETC Source Four LED Lights World's Longest Viking Ship

Around 1025 AD, a fierce 120' Viking warship of the Danish fleet rode the northern waves. Excavated in 1997 from a Roskilde fjord bed, the ship has now been partly restored. A massive steel skeleton has been built around its wooden remains. Roskilde 6 makes a new "voyage," in the National Museum of Denmark's exhibit Viking, June 22 - November 17, 2013. ETC's Source Four LED fixtures, controlled by an ETC Ion console and Unison Paradigm system, bring the vessel to light.

Says lighting designer Hans Henrik Schmidt, "This is the first such use of LED lighting in a museum in Denmark, and exhibition reviews that we've seen which mention the lighting have been overwhelmingly positive."

Schmidt worked with ETC dealer Bico Professionel and the museum's head of AV, Michael Bjørn, to come up with the exciting lighting scheme that would highlight the ship and surrounding exhibits. "The managers were keen to use ETC's energy-efficient LED technology because of the quality of light and appropriate color-rendering index values," explains Schmidt.

But the most important aspect of the lighting from the museum's point of view was that the light output not damage the exhibits, which included the ship and artifacts. "We recommended ETC Source Four LED Lustr+ for their low heat and minimal UV output. Even though they have indigo LED emitters, which would highlight whites just like a black light, there is virtually no UV, which could damage the 1,000-year-old ship."

The Lustr+ fixtures are also used to enhance the backdrop of video projections of animated Viking invasions. "I analyzed the colors in the movie," explains Schmidt, "and reflected them not only in the walls surrounding the screen but also the lighting on the ship itself. For example, when a city burns, or a ray of sunshine is seen in the film, the Lustr+ can produce warm yellows, reds, and oranges in the reflections. And when there is a flash of lighting, we see a strobe effect."

All the lighting was programmed by freelance operator Jan Michael Jensen using an ETC Ion control desk bought by the museum. "Because no one was allowed near the exhibit in case of harming it -- the fixtures all needed to be addressed remotely once they were in situ. RDM came in very handy."

The show was then transferred to a Unison Paradigm system using the snapshot function. "That way, the day-to-day lighting can be operated by minimally trained staff -- such as gallery attendants, cleaners, and security," says Schmidt. "Normally, the system can be started at the beginning of the day using a key-operated switch, and it runs a timed program that contains all cues and triggers for the video performance."

Staff can use the panel to turn the system on or off, but other lighting adjustments can be carried out by authorized personnel via the Ion desk. The system is also designed to work with the existing halogen house lights as required.
